How about Jinan Maochang glasses?
Maochang Glasses Company is a private enterprise, and its boss is surnamed Huang, a southerner. At present, Maochang Glasses Company has more than a dozen chain stores in Jinan, with 80 or 90 employees, and the enterprise scale is acceptable. The price of products is cheaper than that of famous enterprises such as Baomingzhai and Jiang Yukun, but more expensive than ordinary small optical shops. I have worn contact lenses and sunglasses in Maochang, and I feel that the quality is not bad. You can have a look.
